Majority of diamonds (around 80%) are not suited for jewelry because they have too much inclusions and other imperfections so they end up being used in many industries.

Industrial diamonds are not valued for their beauty and their shine but mostly for their hardness, and heat conductivity, because these two properties are much sought after in many industries.

Around 27,000 kg of diamonds is each year used for different industrial purposes.

Synthetic diamonds (diamonds that have been produced in the lab) are also used for industrial purposes, and not just diamonds found in nature.

It is estimated that around 110,000 kg of lab made diamonds is each year used for different industrial purposes.

The demand for jewelry is the main factor that decides the boundary between gem quality and industrial diamonds. For instance, if there is a strong demand for cut diamonds some more or less suitable diamonds will be cut into low-quality or small gemstones rather than being sold for industrial use, because of higher profit.

Most common use of diamonds in industry is for cutting and grinding tools, this is of course because of diamond's hardness as diamonds are the hardest substances on our planet.

Diamonds can be even used as tools to cut other diamonds.

Diamond powder can be used as an abrasive.

Lately the most talked about industrial uses of diamonds include possible use of diamond as a semiconductor suitable to build microchips, or its use as a heat sink in electronics.
